Abstract: PROBLEM TO BE SOLVED: To make a magnetic head device thinner by forming a rib between a magnetic head holding part and an elastically deformed part of a spring part to give rigidity. SOLUTION: A magnetic head 2 of the magnetic head device 1 is supported on a support arm 3 comprising a plate spring material, and is pressed to be in contact with a disc in a state where the arm 3 deformed elastically to apply a magnetic field to the disc.
